Implementations

impl MT19937

pub fn new_with_slice_seed(init_key: &[u32]) -> Self

pub fn seed_slice(&mut self, init_key: &[u32])

initialize by an array with array-length

Trait Implementations

impl Debug for MT19937

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MT19937

fn default() -> Self

Returns the “default value” for a type.

impl RngCore for MT19937

fn next_u32(&mut self) -> u32

Return the next random u32.

fn next_u64(&mut self) -> u64

Return the next random u64.

fn fill_bytes(&mut self, dest: &mut [u8])

Fill dest with random data.

fn try_fill_bytes(&mut self, dest: &mut [u8]) -> Result<(), Error>

impl SeedableRng for MT19937

type Seed = Seed

Seed type, which is restricted to types mutably-dereferencable as u8 arrays (we recommend [u8; N] for some N).

fn from_seed(seed: Self::Seed) -> Self

pub fn seed_from_u64(state: u64) -> Self

Create a new PRNG using a u64 seed.

pub fn from_rng<R>(rng: R) -> Result<Self, Error> where
    R: RngCore, 

Create a new PRNG seeded from another Rng.
